i bet it's not restarting from scratch. do you have proof of that?

you don't have to. condor does this automatically. if you don't
specify transfer_output_files, condor sees any new files that get
created and transfers them for you. if you're in ON_EXIT_OR_EVICT
mode, it will include all these files to be transfered as input the
next time it's run.

that's one thing we don't handle now, and i don't see any good way to
avoid it. these files are just going to be transfered around with
your job until it finally completes. there's currently no way to
specify an "ignore" list or something. it's worse, since you want
them transfered back to your submit machine, you just don't want them
considered input for the future...
